I tried to update my 4.2.1 jailbroken iPhone 4 to 5.1.1, but when I try to do the restore I get error 21. This is very annoying as iPhone is stuck on the "connect to iTunes" screen and is not usable. Please help.

hmm because if you are trying to restore with a custom firmware of 5.1.1 i think the 1600 can be fixed here.

I pressed Shift + Restore and then I am supposed to select a file? I have no idea what to do here.
you have to download the .ipsw file for your device. http://www.felixbruns.de/iPod/firmware/ here they have any firmware for any device. Go select the file you want and download it.When its done, repeat the step (shift+ restore) and choose this file)

if you have any other problem let me know
